WATER-COOLER.

Application led September 10, 1904. Serial No. 223,954.

llo all whom t may concern:

Be it known that I, GEORGE E. SAVAGE, a citizen of the United States,residing at Meriden, in the county of New Haven, State of Connecticut,have invented certain new and useful Improvements in Water-Coolers, ofwhich the following is a full, clear, and exact description.

My invention relates to refrigerating apparatus, and particularly to awater-cooler.

The object of this invention is to construct a cooler for holding waterand ice, so that the water may be reduced in temperature and so that thecooler will befree from what is termed sweating The invention consistsin improvements the principles of which are illustrated in theaccompanying single sheet of drawings. A main casing forms a chamber forice Which surrounds a tank for the water. A cover is provided for theice-chamber and the Watertank and an auxiliary casing with an auxiliarycover provided externally of these, provision being made for thecirculation of air between the main and supplementary casings forpreventing sweating. Above the cooler is supported an auxiliaryreservoir in the form of a water-bottle. This is supported on a yieldingframework.

Figure 1 is a vertical section of the watercooler, showing thewater-bottle or auxiliary reservoir in side elevation. Fig. 2 is a planview of the framework for supporting the reservoir.

1 indicates the water-tank, which is preferably formed of sheet metalcoated with en- I amel inside and out.

2 is the ice-chamber,formed of suitable material and having double wallsWhich form the main casing.

3 is a space between the inner and outer walls of the casing, formingthe ice-chamber,

which space provides thermal insulation. It-

may be, if desired, packed with suitable insulating material.

4 is an auxiliary casing which surrounds the mai-n casing and preventsthe outside air from contacting with and consequently precipitatingmoisture upon the outer side of the main casing.

5 is a base member in the form of a pan, which in this particular formof my invention serves to support the structure.

6 is a faucet or outlet connected with the water-tank 1, through whichthe water may be drawn off.

7 is an overiiow-pipe leading from the icechamber within the main casingfor carrying off the surplus of Water from the melting ice.

8 is an opening into the pan 5, which may serve as the air-inlet to thepan, as well as a drain-pipe for-a suitable tumbler-receptacle. (Notshown.) This taps the air-space below the main casing. y

9 indicates one of a series of holes in the auxiliary casing 4, locatednear the top for permitting circulation of air and preventing the casing4 from reaching too low a temperature.

10 is a cover, preferably formed with double Walls, between which is asuitable insulating material. This cover has a central opening and restsupon the water-tank 1 and covers the top of the ice-chamber. The uppersurface of the cover is preferably sloped off toward the circumference,as shown.

11 is an auxiliary cover which is supported by the main casing 2 andpreferably of the form shown. This has a central opening and has itssides curved, so that moisture condensing upon the inner surface willdrip upon the upper sloping surface of the cover 10, and hence graduallydrip into the ice-chamber.

The frame shown in Fig. 2 consists of a lower ring 12 and an upper ring13, connected by the arms 14 14. The arms 14 serve to support the upperring 13 in a yielding manner and are preferably scroll-shaped, as shown.

15 is an auxiliary reservoir in the form of a Water-bottle inverted withits neck extending into the top Vof the water-tank 1 and preferablyhaving a shoulder centered by the ring 13 of the frame.

16 is a small tube which is preferably emiloyed and carried by asuitable cork which ts Within the neck of the bottle. The water withinthe reservoir 15 can hence flow down into the tank 1 until it reachesthe level of the lower end of the tube 16 or the neck of the bottleincase the neck reaches into the tank, As Water is drawn off from thetank 1 through the outlet 6 the upper level descends and permits theoutside air to pass downward through the central openings in theauxiliary and main covers to take the place of the water which at thesame time flows from the reservoir 15. The reservoir when filled, andparticularly the larger sizes of reservoirs, is of considerable weight,and hence likely to be more readily damaged. The' spring-like supportafforded by the IOO IIO

frame, however, gives a'cushion effect which avoids considerabledifficulty.

In other forms of coolers previously made great difiiculty has beenencountered in the condensation of moisture on the outside. This islikely to oxidize even the finest nickelplate unless the greatest careis taken to keep the outer surface dry. By my construction, however, theauxiliary casing 4 forms the outer visible portion of the cooler, whilethe moisture is condensed upon the outer surface of the main casing 2,and hence drips down into the pan v5.

The advantages of this construction will be apparent to those who areskilled in the art.

What I claim is- 1. In a water-cooler, the combination of a main casingforming an ice-chamber 2, a water-tank 1 mounted therein, adouble-walled cover 10 for said ice-chamber and said watertank,supported by said water-tank and having a central opening, an auxiliarycover 11 supported by the main casing and having a passage for freecommunication of the air between said covers with the outer air, andmeans for supporting an inverted water-bottle with its neck within theopening in cover 10.

2. In a water-cooler, the-cornbination of a' main casing forming anice-chamber 2, a Water-tank l mounted therein, a cover extending oversaid ice-chamber and said watertank but having a central opening, aJframe supported by the casing and formed of rings GEORGE E. SAVAGE.
